Buying used parts
I’ve bought new parts but never used. Until now. I messaged them about a part I was interested in and they replied and gave me a deal I didn’t pass up. Package was good and I would keep doing business with them!

The downpipe fit very well and came with everything I needed. Was also very well built.

Never received parts I orderded and paid for. The parts I did receive were trash and didn’t fit and or has incorrect locations for brackets. No one has returned a email in weeks. Terrible company and terrible quality.

The product got here fast and worked well!!
By Sebastian M.
Fast shipping and product was not damaged, definitely feel the difference while maintaining close to stock exhaust note for normal driving yet deeper when in sport or flooring it . Only thing negative is not a true bolt-on catless dp for the bmw n20 motor. I had to purchase a exhaust pipe adapter with 2 1/2 reduced to 2 1/4 so that it would slide over the dp and slide in the oem midpipe. Also flange on dp to turbo was thicker than stock so using original v-band clamp was a pain I recommend buying a new one. Only lower transmission bracket lined up on the dp but might work if you remove or loosen bracket on tranny.

Great customer service I emailed to ask if a part would fit my car and they helped make sure I got exactly what I needed

Everything with the purchase was amazing! Fast shipping and very happy with the downpipe. I don’t hear any turbo whine, so maybe I need to go catless
